If you're like most UNIX users, you have a job to do aside from exploring your operating system - like analyzing that hot new stock, running another experiment, or typesetting another report. What happens when you have problems?

When You Can't Find Your UNIX System Administrator is written to give you tools for solving problems.

"What you need to know about this book
What you need to know about solving problems
There's no magic in solving user problems:It's good detective work
We describe how best to present your problems to an administrator (for the fastest response and solutions)
We then look at general troubleshooting skills: recreating theproblem, reading error messages, trying obvious answers, and identifying possible factors that could have caused the problem
What you need to know about logging in
Logging in is a series of steps
When you can't log in, there are still things that you can check and fix
We explain checking the power supply
Cables and brightness control
Rebooting to reset a number of parameters changing an .xsession file for X terminal users when to ask for help
We also discuss password files
Selecting a good password and how to change passwords
What you need to know about running programs
You can run any command on the system by using its full pathname
Problems with commands are usually problems with the pointers to this full pathname
We describe where commands reside
Command search paths
Adding directories to your search path
Different versions of the same command
Using aliases for commands
File permissions
And how to fix problems with the TERM environment variable
What you need to know about sharing files
On a multiuser system, you can potentially share any file with any other user
File permissions are security measures that determine who can share what files
We discuss read/write/execute permissions
File ownership
How file owners can change permissions for a group or for the world
And what to do if you don't have permission to access a file
What you need to know about printing
Printing is a multi-step process
You have control over many steps in that process
We discuss how files are translated into a printer language (such as PostScript)
How to test if a file is in PostScript format
How to control what printer a file goes to
How to check the print queue and move or cancel jobs
And simple printer troubleshooting
What you need to know about space and time
On a multiuser system, you share disk space and processing time with other users
Sooner or later, you'll need to know what to do to optimize your use of these resources
We cover how and where files are stored
Checking disk space and the size of your directories
What kind of files to delete or compress if you need to create space
We also show how to deal with a slow system
How to check your processes
What processes are more resource-intensive than others, and how to kill unwanted processes
What you need to know about everyone else
Since you are on a multiuser system, you may need to find out what someone else is doing
We talk about using commands to see if someone on your system is logged on or has read mail
Using the finger command to see who is on another system
Creating a .plan or .project file to tell others about yourself
And finding out who is on a mail alias
What you need to know if you need to know more
